No mapping found for HTTP request with URI while redirect

Question

I have registered following viewResolvewer:

     <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/pages/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

and wrote following controller method:

    @ExceptionHandler(value = Exception.class)
    public String redirectToErrorPage(){
        return "redirect:/errorPage";
    }

When following method executes I see following log:

WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/errorPage] in DispatcherServlet with name 'appServlet'

page with name errorPage.jsp locates under the page folder:

Please explain what do I wrong?

Answer 1

You are redirecting to the the URL "/errorPage", but there is no request mapping for /errorPage. You can add a controller with that request mapping e.g.:

@Controller
public class ErrorPageController {

    @RequestMapping("/errorPage")
    @ResponseStatus(value=HttpStatus.INTERNAL_SERVER_ERROR)
    public String showErrorPage(){
        return "errorPage";
    }
}

Or instead of redirecting, you can just show the error page from your exception handler.

@ExceptionHandler(value = Exception.class)
@ResponseStatus(value=HttpStatus.INTERNAL_SERVER_ERROR)
public String handleException(Exception e){
    return "errorPage";
}
